Description

Technical Field

[0001] This application relates to the technical field of pipeline cleaning equipment, especially underground pipeline cleaning equipment. Background Art

[0002] For pipelines that have been used for a long time, the sludge and rust scale inside the pipes solidify, causing the original pipe diameter to become smaller. The silt sediment in the pipes generates hydrogen sulfide gas, causing environmental pollution and being prone to combustion and explosion. The acid and alkali substances in the wastewater are likely to corrode the pipe walls. The irregular removal of foreign objects in the pipes will cause pipe blockages. Therefore, pipeline cleaning is required. Pipeline cleaning refers to cleaning the pipeline to restore the surface of the pipeline material itself. After cleaning, a dense chemical passivation film is formed on the clean metal surface, which can effectively prevent the recurrence of dirt.

[0003] The existing underground pipeline cleaning process includes the following steps: First, fill the entire pipe network with water (the full pipe water during pressure testing can be utilized). Subsequently, start the circulating water pump for circulating filtration. Repeatedly conduct multiple rough washing cycles. Each time after draining the water, remove all the accumulated impurities in the filtration. Change the water and then conduct a clean water circulation until the solid content in the drained water is close to or equal to the solid content in the flushing water, which is considered qualified. Finally, remove the additional temporary pipes installed and reinstall them to complete the cleaning.

[0004] In the above process, the circulating water is usually filtered by a filter screen. When the content of fine impurities such as sediment in the circulating water is relatively high and the equipment is used for a long time, the filter screen is easily blocked. While its filtration effect decreases, it will also affect the water flow rate per unit time, affecting the cleaning efficiency. Moreover, it is rather troublesome to clean the filter screen. Therefore, an underground pipeline cleaning equipment is proposed for the above problems. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, this application provides an underground pipeline cleaning equipment, which overcomes the deficiencies of the prior art and aims to solve the problem that the filter screen in the cleaning equipment is easily blocked, affecting the circulating cleaning efficiency.

[0006] To achieve the above object, this application provides the following technical solutions:

[0007] The underground pipeline cleaning equipment includes a cleaning pump, a recovery pump, and a filtration tank. The filtration tank includes a tank main body. Inside the tank main body, a first anti-blocking filtration structure, a second anti-blocking filtration structure, and a third anti-blocking filtration structure are fixedly arranged in sequence from right to left. At the bottom of the tank main body, accumulation grooves are provided at positions directly below the first anti-blocking filtration structure, the second anti-blocking filtration structure, and the third anti-blocking filtration structure.

[0008] By adopting the above technical solution, the cleaning pump and the recycling pump can jointly drive the cleaning water to circulate. When the flowing water finishes cleaning and enters the main body of the pool, the first anti-blocking filtering structure, the second anti-blocking filtering structure, and the third anti-blocking filtering structure can respectively filter large, medium, and small diameter particles therein, avoiding blockage caused by a large number of impurity particles being intercepted at one time. Moreover, the cleaning water needs to surge upward to reach the filtering structure for filtering. During this process, some impurity particles with a large density will sink into the accumulation tank and cannot reach the filtering structure. At the same time, when the cleaning pump and the recycling pump stop working, the water above the filtering structure will fall under the action of gravity, flushing the impurity particles on the filtering structure and playing a role of self-cleaning.

[0009] As a preferred technical solution of the present application, the first anti-blocking filtering structure, the second anti-blocking filtering structure, and the third anti-blocking filtering structure have the same structure, and each includes a front baffle and a rear baffle. An inclined baffle is fixedly arranged between the front baffle and the rear baffle, and a filter screen is detachably embedded in the inclined baffle.

[0010] By adopting the above technical solution, the cleaning water needs to surge upward for a certain distance before reaching the filter screen. During this process, some relatively heavy impurity particles will sink, thereby reducing the working burden of the filter screen. At the same time, when the cleaning pump and the recycling pump stop working, the water above the filter screen will fall under the action of gravity, flushing the impurity particles on the filter screen and playing a role of self-cleaning and anti-blocking.

[0011] As a preferred technical solution of the present application, the bottom and both sides of the front baffle are hermetically connected to the inner wall of the main body of the pool, and both sides of the rear baffle are hermetically connected to the inner wall of the main body of the pool, and there is a water passing opening between the bottom of the rear baffle and the bottom of the pool body.

[0012] By adopting the above technical solution, a complete water flow path can be formed, that is, the cleaning water needs to surge upward for a certain distance along the channel between the front baffle and the rear baffle before reaching the filter screen.

[0013] As a preferred technical solution of the present application, the pore diameters of the filter screens on the first anti-blocking filtering structure, the second anti-blocking filtering structure, and the third anti-blocking filtering structure decrease in sequence.

[0014] By adopting the above technical solution, large, medium, and small diameter particles in the cleaning water can be respectively filtered, avoiding blockage caused by a large number of impurity particles being intercepted at one time.

[0015] As a preferred technical solution of the present application, a cleaning port communicating with the accumulation tank is opened at the bottom of the main body of the pool, and a sealed cover is rotatably arranged outside the cleaning port.

[0016] By adopting the above technical solution, the convenience of cleaning the deposits in the accumulation tank can be improved through the cleaning port, that is, when cleaning, the sealed cover can be opened to take out the deposits in the accumulation tank, and when the cleaning is completed, closing the sealed cover can prevent the cleaning water from flowing out through the cleaning port.

[0017] As a preferred technical solution of the present application, the output interface of the cleaning pump is hermetically connected to an output pipe, the input interface of the cleaning pump is hermetically connected to a water suction pipe, and one end of the water suction pipe far from the cleaning pump is hermetically communicated with the left side of the filter tank.

[0018] By adopting the above technical solution, the cleaning pump can extract, pressurize and spray the filtered cleaning water through the water suction pipe and spray it out from the output pipe to wash the pipeline.

[0019] As a preferred technical solution of the present application, the input interface of the recycling pump is hermetically connected to a recycling pipe, the output interface of the recycling pump is hermetically connected to a drain pipe, and one end of the drain pipe far from the recycling pump is hermetically communicated with the right side of the filter tank.

[0020] By adopting the above technical solution, the recycling pump can extract, pressurize and transport the cleaning water that has completed the flushing through the recycling pipe and send it into the main body of the tank, and at the same time can apply pressure to the water in the main body of the tank to improve its filtering effect.

[0021] The beneficial effects of the present application: When the flowing water completes the cleaning and enters the main body of the tank, the first anti-clogging filtering structure, the second anti-clogging filtering structure and the third anti-clogging filtering structure can respectively filter large, medium and small diameter particles therein, avoiding blockage caused by a large number of impurity particles being intercepted at one time; and the cleaning water needs to surge up to reach the filtering structure to be filtered, and during this process, some impurity particles with a large density will sink into the accumulation tank and cannot reach the filtering structure; at the same time, when the cleaning pump and the recycling pump stop working, the water above the filtering structure will fall under the action of gravity, washing down the impurity particles on the filtering structure and playing a role of self-cleaning.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] Refer to Figure 1-2 , the underground pipeline cleaning equipment includes a cleaning pump 1, a recycling pump 2 and a filter tank 3. The filter tank 3 includes a tank main body 31. Inside the tank main body 31, a first anti-clogging filter structure 41, a second anti-clogging filter structure 42 and a third anti-clogging filter structure 43 are fixedly arranged in sequence from right to left. At the bottom of the tank main body 31, accumulation tanks 32 are fixedly opened at positions directly below the first anti-clogging filter structure 41, the second anti-clogging filter structure 42 and the third anti-clogging filter structure 43; it can drive the cleaning water to circulate by the combined action of the cleaning pump 1 and the recycling pump 2. When the flowing water finishes cleaning and enters the tank main body 31, the first anti-clogging filter structure 41, the second anti-clogging filter structure 42 and the third anti-clogging filter structure 43 can respectively filter large, medium and small diameter particles therein, avoiding blockage caused by a large number of impurity particles being intercepted at one time. Moreover, the cleaning water needs to surge up to reach the filter structure for filtration. During this process, some impurity particles with a large density will sink into the accumulation tank 32 and cannot reach the filter structure. At the same time, when the cleaning pump 1 and the recycling pump 2 stop working, the water above the filter structure will fall under the action of gravity, flushing the impurity particles on the filter structure and playing a self-cleaning role.

[0029] Refer to Figure 3, the first anti-clogging filter structure 41, the second anti-clogging filter structure 42 and the third anti-clogging filter structure 43 have the same structure, all including a front baffle 401 and a rear baffle 402. A slant baffle 403 is fixedly arranged between the front baffle 401 and the rear baffle 402, and a filter screen 404 is detachably embedded in the slant baffle 403. By adopting the above technical solution, the cleaning water needs to surge upward for a certain distance before reaching the filter screen 404. During this process, some heavier impurity particles will sink, thereby reducing the working burden of the filter screen 404. At the same time, when the cleaning pump 1 and the recycling pump 2 stop working, the water above the filter screen 404 will fall under the action of gravity, flushing the impurity particles on the filter screen 404, playing a role of self-cleaning and anti-clogging.

[0030] Refer to Figure 3 , the bottom and both sides of the front baffle 401 are hermetically connected to the inner wall of the pool body 31, and both sides of the rear baffle 402 are hermetically connected to the inner wall of the pool body 31 and there is a water passing port 405 between the bottom of the rear baffle 402 and the bottom of the pool body 31. The above structural form can form a complete water flow path, that is, the cleaning water needs to surge upward for a certain distance along the channel between the front baffle 401 and the rear baffle 402 before reaching the filter screen 404. In particular, the pore diameters of the filter screens 404 on the first anti-clogging filter structure 41, the second anti-clogging filter structure 42 and the third anti-clogging filter structure 43 decrease in sequence, which can play a role in filtering large, medium and small diameter particles in the cleaning water respectively, avoiding the blockage caused by a large number of impurity particles being intercepted at one time.

[0031] Refer to Figure 2 , Figure 4 , a cleaning port 33 communicating with the accumulation tank 32 is opened at the bottom of the pool body 31, and a sealed cover 34 is rotatably arranged outside the cleaning port 33. The cleaning port 33 can improve the convenience of cleaning the accumulated materials in the accumulation tank 32, that is, when cleaning, the sealed cover 34 is opened to take out the accumulated materials in the accumulation tank 32, and when the cleaning is completed, the sealed cover 34 is closed to prevent the cleaning water from flowing out of the cleaning port 33.

[0032] Refer to Figure 1 , an output pipe 11 is hermetically connected to the output interface of the cleaning pump 1, a water suction pipe 12 is hermetically connected to the input interface of the cleaning pump 1, and one end of the water suction pipe 12 far away from the cleaning pump 1 is hermetically communicated with the left side of the filter pool 3. The cleaning pump 1 can pump out and pressurize the filtered cleaning water through the water suction pipe 12 and spray it out from the output pipe 11 to wash the pipeline. At the same time, a recycling pipe 21 is hermetically connected to the input interface of the recycling pump 2, a drain pipe 22 is hermetically connected to the output interface of the recycling pump 2, and one end of the drain pipe 22 far away from the recycling pump 2 is hermetically communicated with the right side of the filter pool 3. The recycling pump 2 can pump out and pressurize the cleaning water that has completed the flushing through the recycling pipe 21 and transport it into the pool body 31, and at the same time can apply pressure to the water in the pool body 31 to improve its filtering effect.

[0033] Working principle: During cleaning, the cleaning pump 1 can extract the filtered cleaning water in the pool main body 31 through the suction pipe 12, pressurize it, and spray it out from the output pipe 11 to flush the pipeline. Synchronously, the recovery pump 2 can extract the cleaning water that has completed flushing through the recovery pipe 21, pressurize it, and transport it to the pool main body 31 for filtration. At the same time, it can apply pressure to the water in the pool main body 31 to improve its filtration effect;

[0034] When the flowing water finishes cleaning and enters the pool main body 31, the first anti-blocking filtration structure 41, the second anti-blocking filtration structure 42, and the third anti-blocking filtration structure 43 can respectively filter large, medium, and small diameter particles therein, avoiding blockage caused by a large number of impurity particles being intercepted at one time; In particular, the cleaning water needs to surge upward for a certain distance before reaching the filter screen 404. During this process, some heavier impurity particles will sink, thereby reducing the working burden of the filter screen 404; At the same time, when the cleaning pump 1 and the recovery pump 2 stop working, the water above the filter screen 404 will fall under the action of gravity, washing down the impurity particles on the filter screen 404, playing a role of self-cleaning and anti-blocking;

[0035] In addition, the accumulation tank 32 needs to be cleaned regularly. When cleaning, just open the sealed cover 34 to take out the accumulated materials in the accumulation tank 32. When the cleaning is completed, closing the sealed cover 34 can prevent the cleaning water from flowing out from the cleaning port 33.

[0036] The above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
